your good plugins doesn't work very good.
From 3.0.6 to 3.0.8 it has the same problem. The banner doesn't run, but it is always the same.
You can see the difference from http://www.automotivespace.it (3.0.8) and http://www.automotivespace.eu (3.0.5).
I make your advice and I deactived plugin and I emptied cache....but the result is the same.
Many thanks for your help.
